McRo decision expected to clarify abstract idea doctrine under Alice

By Zachary Silbersher
January 5, 2016

federal-circuit-front-steps-335To say that the Supreme Court’s Alice decision has shaken up the patent world is an understatement. While that much is fairly undisputed, what has confounded patent lawyers and courts alike is that Alice was short on actual guidance for deciphering the difficult question of whether a claim is directed to an abstract idea. Past articles have a highlighted these challenges faced by patent owners and practitioners.

A case currently pending before the Federal Circuit is anticipated to provide greater guidance into the answer to this question, namely, how district courts should determine whether a claim is directed to an abstract idea. The case, McRo, Inc. v. Bandai Namco Games America, No. 2015-1080, recently heard oral argument on December 11, 2015. The panel’s questioning indicated that its anticipated decision may provide greater insight into how district courts are to determine whether a claim is, in fact, directed to an abstract idea. As a result, the opinion may also loosen the noose of Alice a bit, and make it slightly more difficult for defendants to short-circuit patent litigations with early motions directed to ineligible subject matter.

McRo involved two tracks of consolidated cases against numerous video game developers. The plaintiff, McRo, Inc., d.b.a. Planet Blue, asserted two patents, U.S. Patent Nos. 6,307,576 and 6,611,278. The patents are directed to automatic three-dimensional lip-synchronization for animated characters. Whereas prior art lip-synchronization required manually synchronizing an animated character’s lips and facial expressions to specific phonemes, the patents are directed to rules for automating that process. Defendants moved for judgment on the pleadings on the grounds that the asserted ‘576 and ‘278 Patents were directed to ineligible subject matter under section 101. The Honorable George H. Wu, for the Central District of California, granted the motion.

In his opinion invalidating the patents as directed to ineligible subject matter, Judge Wu lamented the apparent lack of tangible guidance on the application of section 101. Recognizing that the Supreme Court has now endorsed section 101 as an important tool for protecting the role of patents as fostering follow-on innovation, he nevertheless observed that “District Courts and the Federal Circuit are now left with the task of figuring out when the ‘two-part’ test is satisfied.” (Slip Op. at 10). District Courts are often tasked with the chore of determining the contours of a broad principle enunciated by a higher court. But this case is noteworthy because, during oral argument before the Federal Circuit, the Court also expressed concern that it is not clear when a patent claim can decidedly be said to be directed to an abstract idea under step one of the two-part test.

At the district court, Defendants’ principal argument was that Planet Blue’s patents do nothing more than claim the application of “rules” for automatic 3D lip-synchronization, without specifying what those rules actually are. Judge Wu did not find that the claims, on their face, are directed to the abstract idea of using “rules” to automate lip-synchronization. Instead, he found the claims limited to automating lip-synchronization using specific inputs, including: 1) a timed phoneme sequence, 2) setting morph weight sets at certain key frames and 3) interpolating between keyframes. But those inputs already existed in the prior art. Yet, under the prior art method, the morph weight sets were manually set at certain keyframes. The patents simply claimed allegedly unspecified rules for setting those morph weight sets. Judge Wu stated, “A consideration of the prior art recited in the patents shows that the point of novelty here is the idea of using rules, including timing rules, to automate the process of generating keyframes.” (Slip Op. at 17). Thus, despite finding the claims are “tangible, each covering an approach to automated three-dimensional computer animation, which is a specific technological process,” (Slip Op. 13), Judge Wu nevertheless found the inventive feature of the claims was directed to an abstract idea. But this is only because he first stripped the claims of the “tangible” aspects already existing in the prior art.

Ineligibility, at least on its face, has little to do with novelty. Indeed, as Judge Wu rightly observed, Einstein’s celebrated reduction of relativity to the mathematical relation, E = mc2, was an unquestionable stroke of genius, but no one would contend that section 101 would have sanctioned a patent for that.   (Slip Op. at 20). Yet, Judge Wu nevertheless concluded that the section 101 two-part-test must be performed within the context of the prior art. Because of this, he took the radical step of stripping the claim of its conventional elements before looking at it again and concluding that, adequately stripped, it is indeed directed to an abstract idea without “significantly more.”

Writers on this blog, among others, have observed that Judge Wu’s analysis is “not Mayo’s two part test.” During oral argument before the Federal Circuit, the panel also questioned whether Judge Wu erroneously injected a third step into the two-part test. The panel expressed this concern to both Plaintiff’s and Defendants’ counsel. The implication from the Court’s questioning was, by backing out conventional or prior art elements of the claim during step one, and focusing only on those elements within the claim that did not exist in the prior art, Judge Wu erred by only considering whether a portion of the claim was directed to an abstract idea, rather than considering the claim as a whole.

Interestingly, Judge Wu’s analysis was not without reason. He observed that patent claims often recite lots of old material with the addition of a single novel element. If that single novel element simply claims an abstract idea, then that exacerbates the precise concerns underlying section 101. Judge Wu appears to have suggested that patentees should not, in theory, be able to circumvent section 101 by reciting tangible, non-abstract prior art, and then merely tacking on a functional limitation as the point of novelty that preempts all tangible solutions that would satisfy that functional limitation. As Judge Wu states, “[a]n abstract idea is the extreme case of functional language.” (Slip Op. at 15). An example would presumably be a claim directed to an automobile, reciting all the tangible pieces and equipment built into that automobile, with a final step that recites, “wherein said processor contains rules for automating driving of said automobile.”

One thing is for sure—Judge Wu’s analysis raised the question of when, exactly, claims can be safely said to be directed to an abstract idea under step one of the two-part test. During oral argument before the Federal Circuit, the panel expressed concern over that very inquiry. One Judge asked whether district courts are to ask whether the “purpose” of the invention is abstract, or something else. The Judges further asked, assuming Judge Wu’s method for assessing whether the claims are directed to abstract ideas was incorrect, then what method should the district court have followed? The Federal Circuit’s questioning echoed some of the same laments by Judge Wu, namely that without tangible guidance on how to assess whether a claim is directed to an “abstract idea,” it may be more like Justice Stewart’s famous phrase, “I know it when I see it.” (Slip Op. at 8, quoting Jacobellis v. State of Ohio, 378 U.S. 184, 197 (1964) (Stewart, J. concurring)).

During oral argument, the Federal Circuit panel questioned Judge Wu’s analysis on another ground that may make it more difficult for district courts to “Alice”—especially early in a case—a patent in the future. The panel inquired whether the claims were not yet adequately construed to determine whether they were ineligible. Defendants argued that Planet Blue’s patents do nothing more than claim the application of “rules” for automatic 3D lip-synchronization, without specifying what those rules actually are. Without necessarily disagreeing with that, the Court asked if there exists a permissible claim construction that, if adopted, would delimit those rules sufficiently so that the claims could not be said to preempt all uses of rules for automatic lip-synchronization. While Judge Wu did construe the claims at the district court, the Federal Circuit panel nevertheless questioned whether a claim construction existed that could narrow the “rules” to be applied by the claims, suggesting Judge Wu’s decision may, at the very least, require remand.

Overall, the Federal Circuit is likely to issue additional guidance on how district courts are to determine the first-step—whether the claim is directed to an abstract idea. The panel’s questioning suggests two broad principles may emerge. First, the first step of section 101 analysis must consider the claim as a whole. Claims should not be stripped of conventional elements before deciding whether they are directed to an abstract idea. The result of this will likely narrow the field of patents that are subject to invalidation under Alice, especially claims that recite tangible conventional structure coupled with inventive elements that can be characterized as purely functional.

Second, district courts may be admonished to determine whether any possible claim constructions exist that would adequately limit the claims so they cannot preempt all solutions to a functional claim element. While avoiding a bright-line rule that claim construction must precede a motion under Alice, district courts might be reminded that proper claim construction must take into consideration whether the claims can be sufficiently delimited to no longer preempt an abstract idea. Interestingly, claim construction in the context of an Alice decision could put a plaintiff and defendants at odds with their own infringement and invalidity arguments.

    This whole abstract stuff is not law. I was recently told by an examiner that processing data is just an idea. Doesn’t matter what you do with it–you know like generate an office action; it is all just an abstract idea.

    Just ridiculous nonsense that is being used to cripple our patent system. Benson is at the heart of this.

  2. Night Writer January 5, 2016 1:21 pm

    “so that the claims could not be said to preempt all uses of rules for automatic lip-synchronization. ”

    This statement hits at the heart of why this abstract stuff is nonsense. There are two possibilities: 1) the specification has enabled the rules that are being used by the accused device; 2) the specification does not enable the rules that are being used by the accused device. (With all the stuff a person of ordinary skill knew at the time of the application.)

    Now, simple, 1) you infringe. 2) the claims are too broad and invalidated. That is patent law. (Or what was formally called patent law in this country.)

    I’d earlier written about this one.

    That’s an issue of written description, enablement and overbreadth of claims.
    But not 101 subject matter.

  6. Edward Heller January 6, 2016 6:37 am

    This case illustrates well that Bilski should have simply decided that the claims before it there were directed to a business method and that business methods were nonstatutory subject matter. But instead Bilski introduced the term “abstract” as an independent requirement of 101 without explaining what abstract meant. Thus we have this case where the subject matter as a whole clearly is directed to a technological innovation, but nevertheless the claim has been declared to be ineligible under the Bilski/Alice test.

    This is not to say that the claims here should not be invalidated under other portions of the statute, such as written description or enablement. But these issues should not be decided under 101 in my humble opinion.

  7. Night Writer January 6, 2016 7:09 am

    Ed, no. What is a business method? What this case illustrates is that Bilski and Alice are political cases and not law. Stick to basic patent law of finding elements and making 103 arguments and stop trying to categorize inventions to find them invalid.

    And in Bilski what they should have done is remanded back to the dist. ct. for finding it invalid under 103.

    How can the Royal Nine do that with a straight face in view of 35 USC 273? The fact is they can’t (in spite of Stevens disingenuous opinion to the contrary), as was even recognized by Scalia in view of his strange concurrence.

    Hey Zachary,

    You might expect clarification by the Federal Circuit in McRo, and we “mere mortals” could use it when it comes to what is (and more importantly what is not) an “abstract idea.” But given what we’ve seen so far, I wouldn’t hold my breath.

    Indeed, especially in an IPR, where the opportunity to change those assertion positions during the proceeding does not exist.

    P.S. Why cannot the Fed. Cir. remand cases with feckless specs for proper and prompt consideration of a 112 S.J. instead of only considering 101?

  14. Edward Heller January 6, 2016 2:04 pm

    EG, Well, but for 273 …

    As anybody that is part of the process in enacting 35 USC §273 in 1999, would know is that there was an effort to enact broad prior user rights that was opposed by interest groups that relied on the enforceability of patents. In order to get consensus that we needed some form prior user rights, those in favor of prior user rights and those against agreed on a compromise that prior user rights were needed at least with respect to so-called business method patents because State Street Bank had unexpectedly overturned the long settled law that business methods were not patentable subject matter.

    This was hardly an endorsement of that the Federal Circuit was right in overturning the business method exception, but a recognition that unless the Supreme Court eventually reversed State Street Bank, Congress was not going to overturn that case directly because of its unwillingness to touch 101 in any way. Thus the best people could do to minimize the damage of State Street Bank was to authorize prior user rights.

    That effort boomeranged in a big way in Bilski. The controversy regarding “abstract” is a direct consequence of that compromise in 1999.

  15. Curious January 6, 2016 3:03 pm

    This case illustrates well that Bilski should have simply decided that the claims before it there were directed to a business method and that business methods were nonstatutory subject matter.
    Except there is no explicit statutory justification to support such a decision. Instead, SCOTUS had to “interpret” the statute to find unwritten exceptions and proceed from there.

  16. Edward Heller January 6, 2016 3:05 pm

    Curious, what the Kennedy majority ended up doing in my opinion was virtually unconstitutional because if business methods are statutory, that should have ended the matter.

  17. A Rational Person January 6, 2016 4:26 pm

    Edward@16 Given that the constitution says whatever a majority of Supreme Court justices interpret it to say, a majority opinion by the Supreme Court is always “constitutional”.


  18. step back January 6, 2016 4:37 pm

    ARP @#17

    You know that cannot be true.
    The Constitution provides a specific process for amendment thereof. Majority vote by the SCrOTUSi is not it.

    IIRC, there is a ratification needed by 2/3rds of the state assemblies.

  19. Curious January 6, 2016 4:37 pm

    what the Kennedy majority ended up doing in my opinion was virtually unconstitutional
    Virtually unconstitutional = constitutional when SCOTUS says so (see RP’s comment # 17). Regardless, there is no basis in statutory law or policy for making “business methods” (whatever that means — I’ve been looking for a definition on that one for nearly a decade) unpatentable subject matter.

    If you have a definition of “business method” and a policy position as to why a business method should not be patented, then I would like to hear it — just don’t go looking to 35 USC.

  20. A Rational Person January 6, 2016 4:58 pm


    The damage was caused by the courts creating the “business method exception” in the first place. When the courts created the business method exception, they did not foresee a world in which business methods that may have once been implemented by pen and paper, could one day be implemented by a machine employing registers, switches or software, i.e., something that should be considered patent eligible by any reasonable interpretation of 35 USC 101 and by any reasonable statute determining patent eligibility.

    In addition,why is it logical or rational that small piece of metal with a pointed end and hole at the other end (a needle) be “patent eligible” but a complex software system that would improve the interactions of thousands of users with an organization and with various databases controlled by that organization, such as system that would improve the USPTO’s efiling system, Public Pair and Private Pair systems not be patent eligible?

  21. A Rational Person January 6, 2016 5:09 pm


    I agree 100%. In fact, if you try to find a definition of “business method” using Google search, all of the results relate to “business method patent” which is a tip off that the whole concept of a “business method patent” is mainly based on the courts not liking particular types of inventions.

    So, as best I can tell, the best definition of the term “business method” I can come up with is: “A type method that a court has decided is not patent eligible, but the court has also decided is not an application of law of nature.”


  22. Edward Heller January 6, 2016 5:15 pm

    Rational, the BM “exception” (not really an exception) always said that the invention had to be in the means. Alice has restored this part of the test while leaving open just what abstract is.

    You argue that new means needs protection. I do not disagree, but the problem is how to protect the means without protecting the method.

  23. A Rational Person January 6, 2016 5:28 pm


    1. What is the definition of a “business method”?

    2. What is your support outside of the courts for this definition?

    3. Why is the business method “exception” not an exception? 35 USC 101 does not specifically mention business methods but does state that “Whoever inventors or discovers ANY . . . new or useful process . . . or ANY new or useful improvement thereof, may obtain a patent therefor . . . .”

    A method that would be useful in business sounds pretty useful to me? In fact, why would most people spend money obtaining a patent covering a method that would not be useful in business?

  24. Edward Heller January 6, 2016 5:41 pm

    Rational, the courts held that a method of doing business was not an Art. That was long ago.

    Non statutory.

    Not an exception.

  25. Edward Heller January 6, 2016 5:44 pm

    But you do raise a good point about any definition of business method that would be subject to a per se exclusion. I think this might have been why Kennedy did not go with Stevens.

  26. Night Writer January 6, 2016 9:38 pm

    Edward you have a habit of stating your judicial activism as if it is law. Your #24 and #25 are not the law and the SCOTUS said as much in Bilski.

    That the Supreme Court can do no wrong (the infallibility principle) is – and must be – wrong.

    The Court is NOT above the law – ALL three branches are beneath the Constitution.

  28. Edward Heller January 7, 2016 8:52 am

    Night, you are completely wrong. The courts did in fact rule long ago as I stated that business methods were non statutory. That is why State Street Bank has to “overrule” for example, Hotel Security and its progeny. Also see the cases cited by Dyk in his dissent in Bilski.

  29. Edward Heller January 7, 2016 8:55 am

  30. Night Writer January 7, 2016 9:02 am

    Section 101 similarly precludes the broad contention that the term “process” categorically excludes business methods. –Bilski

    Ned, you are a good attorney except for when you put on your 101 hat and start generating nonsense.

  31. Edward Heller January 7, 2016 9:12 am

    Night, the ’52 Act was not written on a blank slate. Congress did not intend to change the law regarding 101 when it reenacted the statute that been in place since the founding. It changed the word Art to “process” only because the Supreme Court had used the term “process” rather than Art in its cases.

  32. A Rational Person January 7, 2016 9:31 am


    If the courts exclude a type of process, i.e., a “business method”, whatever that is, and the statute says “ANY” process is statutory, then the courts have created a judicial exception to the statute.

    On the above fact situation in any other field of law we would certainly refer to this as the courts creating a judicial exception to the explicit wording of the statute.

    Yes, this was done “long ago” but it was wrong then, it is wrong now, and it is one of reasons we are in the mess we are in. And the fact that even though this was done by the courts “long ago”, the courts can still not provide a definition of what a “business method” is shows just a bad a mistake their creating a “business method” exception was.

    Furthermore, whatever harm the courts sought to avoid by creating the “business method” exception has now been dwarfed by the consequences of creating the business method exception, i.e., we now have a patent system in courts are making decisions about the validity of patents based on no evidence and in complete disregard to statutory law.

    How much worse could thing have been if the courts had not created the “business method” exception? 35 USC 102 and 35 USC 102 have not been repealed, so the methods would still have to be novel and nonobvious. In addition, as more business method patent applications were filed, the published prior art grows to take care of the courts’ hypothetical but seldom seen “boogeyman” (boogey-patent?) that preempts a field of human endeavor.

  33. Curious January 7, 2016 9:32 am

    Ed — despite several people asking, you’ve still yet to come up with a definition of a “business method.” You’ve also said that “[t]he courts did in fact rule long ago as I stated that business methods were non statutory.” How can a court rule “something” was non statutory when they don’t even define what that “something” is.

    Regardless, you do realize that statutory law does prevail (a point that anon keeps making yet you keep ignoring) so we need to look to 35 USC 101. Regardless, I would still like to know what case(s) explicitly holds that business methods, as a class of invention, are unpatentable.

    You did mention Hotel Security, so let me discuss that one. Hotel Security was a 2nd Circuit case from 1908 — not my idea rock solid precedent. Also, they were dealing with different law then:
    Section 4886 of the Revised Statutes (U.S. Comp. St. 1901, p. 3382) provides, under certain conditions, that “any person who has invented or discovered any new and useful art, machine, manufacture or composition of matter”

    I’ve read the Hotel Security case a few times and it reminds me of the rambling prose prevalent during those times. Perhaps you overlooked this statement:
    If at the time of Hicks’ application, there had been no system of bookkeeping of any kind in restaurants, we would be confronted with the question whether a new and useful system of cash-registering and account-checking is such an art as is patentable under the statute. This question seems never to have been decided by a controlling authority and its decision is not necessary now unless we find that Hicks has made a contribution to the art which is new and useful. We are decidedly of the opinion that he has not, the overwhelming weight of authority being that claims granted for such improvements as he has made are invalid for lack of patentability
    I’m reading this to say that their holding isn’t based upon whether “a new and useful system of cash-registering and account-checking [i.e., business method] is such an art as is patentable under the statute” but on the improvements not being new. It seems that you have been focusing on dicta in Hotel Security — not the holding.

  34. Anon January 7, 2016 9:38 am

    Mr. Heller,

    You rely on dissents and bogus interpretations of the law.

    Your position in regards to business methods has been thoroughly debunked on “the other blog.”

    Must we be exposed to the same foundation-less rhetoric here as well?

  35. Night Writer January 7, 2016 9:39 am

    Thanks Curious for taking the time to pull that out. Bilski has a history of patentability too that says business methods have never been excluded categorically.

    I am afraid Ned is part of the judicial activist that are fabricating law and facts rather than going to Congress.

  36. Edward Heller January 7, 2016 9:53 am

    I think I did mention that the way the Bilski majority decided the case — that nominally all processes were patentable that the only recognized “exclusions” were laws of nature, natural phenomena and principles in the abstract — is why we are in the mess we are in today.

    If we are going to make exceptions, we would have to have a definition, but there is no definition of abstract let alone a definition of business method. Either approach of categorical exclusions is wrong. I will say that again, wrong and IMHO, unconstitutional.

    This is not to say that the lower courts had not found business methods to be nonstatutory. They did. Not only Hotel Security, but the cases cited by Judge Mayer in Bilski. There were not just one case, but numbers of cases including an opinion by the Commissioner of Patents early on.

    Obviously, one cannot categorically exclude “business methods;” but one can determine whether a particular invention is directed to patentable subject matter.

  37. Edward Heller January 7, 2016 9:54 am

    And, to be sure, there were working definitions of Art, Machine, Manufacture and Composition.

  38. Night Writer January 7, 2016 10:10 am

    One of the biggest things too why this judicial activist stuff is nonsense is that we are talking about machines performing these operations. The courts have attempted to dismiss this, but any person that knows anything about science and technology knows that this is profound. It means the methods and machines will evolve to be very different with the machines than without the machines. In fact, I would say anyone that does not acknowledge this is cannot claim to be either science literate. They are members of the cult of the scientific illiterate.

  39. Night Writer January 7, 2016 10:13 am

    Ned, please. You are blabbering nonsense at this point and contradicting yourself. Sad to see. Grow-up and revoke your membership to the cult of the scientific illiterate and the cult of the judicial activist.

  40. A Rational Person January 7, 2016 10:43 am

    Night Writer@38

    Further to your point. a claim such as the following would be shot down by many judges based on the Supreme Court’s “reasoning” in Alice as being “patent ineligible,” even though had this claim been filed 1953 it should not only have been patent eligible under 35 USC 101 but patentable under 35 USC 102 and 35 USC 103:

    1. A method comprising a electronic device:
    displaying text on a visual display device in real-time with proportional spacing and kerning as the text is input into the electronic device.

    If you eliminate the “electronic device”, the above method can be performed by a human with a pencil and paper.

    But anyone who understands what the state of computer technology was in 1952 would understand that to perform the method of claim 1 in an electronic machine would have been a major technological achievement.

  41. Night Writer January 7, 2016 11:08 am

    A rational person: it is also a good example of the fact that writing/printing displaying text is different with the information processing machines than without them. Business methods have already evolved with the machines past what they could be without the machines and will continue to do so. The courts are ignoring this point intentionally for their judicial activism. Shameful really. No science literate person would take any stock in the court’s phase of merely apply a computer. Any science literate person knows that phrase is ridiculous.

    It would appear that the word “merely”, as in the phrase ‘merely apply it on a computer’ inherently incorporates by reference Justice Merlin Kennedy’s 2nd year engineering student who can code anything and everything on a geriatric computer over any given weekend once given the abstract idea.
